The skit features a Lean on Me duet, Donald Trump impersonations and a cameo from Darrell Hammond as a Bill Clinton who flees, “Oh my God, they’re multiplying.”

Donald Trump and Taran Killam/Darrell Hammond

Donald Trump hosted the show in November, appearing alongside doppelgängers Taran Killam and Darrell Hammond in his opening monologue.

“They just told, Donald—other Donald. They just told me—this is very interesting—that now that I’m here, this is actually the best monologue in SNL history. Can you believe that? Pretty great,” Killam says.

“When I signed that exec order banning cloning research, it was too late to do anything about an experiment or two that had already been started,” Bill Clinton said. “But one of them has come in handy in moments like this. Bill, would you mind?”

Hammond drew laughter as he took the president’s place at the podium to finish the speech, gesturing with his fist and biting his lip.

In an interview with TIME last year, Hammond said the key to a Bill Clinton impersonation was perfecting the “vocal crinkle.”

“There’s no one like him, so on any level you can’t really compare,” Hammond said.

Sarah Palin and Tiny Fey

Tina Fey famously impersonated Alaska Gov. Sarah Palin when she was the vice presidential nominee for Republican candidate John McCain.

Wearing the same red blazer and American flag pin as the comedian, Palinmade a cameo on Saturday Night Live in October 2008, interrupting a press conference and prompting Fey to cede the podium to the real-life governor.

“Now I’m not going to take any of your questions,” Palin said. “But I do want to take this opportunity to say, live from New York, it’s Saturday night.”

In the same episode, the governor bounced along while Amy Poehler performed a Palin-inspired rap about shooting moose, seeing Russia from her porch, and running alongside McCain.

Barack Obama and Fred Armisen

Fred Armisen, who impersonated President Barack Obama on Saturday Night Live for years, said he has met the president a couple of times, and he said Malia Obama is apparently a fan of the impression.

“I met him recently, and he was so nice about it and cool,” Armisen said in an interview with the Daily Beast last year. “And then I met him before I started doing the impression of him when he was a guest on SNL for a moment. But he told me recently that Malia would do my impression of him to him. It was really nice.”
